3 Foreword This document (EN 15079:2007) has been prepared by Technical Committee CEN/TC 133 “Copper and copper alloys”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2007, and conflicting national standards shall be withdrawn at the latest by November 2007. Within its programme of work, Technical Committee CEN/TC 133 requested CEN/TC 133/WG 10 "Methods of analysis" to prepare this standard: EN 15079, Copper and copper alloys — Analysis by spark source optical emission spectrometry (S-OES). According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Repub-lic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
The following referenced documents are indispensable for the application of this document. For dated refer-ences, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 1811-1, Copper and copper alloys — Selection and preparation of samples for chemical analysis — Part 1: Sampling of cast unwrought products ISO 1811-2, Copper and copper alloys — Selection and preparation of samples for chemical analysis — Part 2: Sampling of wrought products and castings NOTE Informative reference to documents used in the preparation of this standard, and cited at the appropriate places in the text, are listed in the Bibliography. 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 reference material material, one or more of whose property values are sufficiently homogeneous and well established to be used for the calibration of an apparatus, the assessment of a measurement method, or for assigning values to materials 3.2 certified reference material reference material, accompanied by a certificate, one or more of whose property values are certified by at least one procedure which establishes its traceability to an accurate realization of the unit in which the prop-erty values are expressed, and for which each certified value is accompanied by an uncertainty at a stated level of confidence 3.3 test sample representative quantity of material for testing purposes 3.4 drift control samples spectrometer control samples series of homogeneous specimens that contain all the elements which have been calibrated and that cover the low and high concentrations of the calibration range for each element, to be used in detecting variations over time NOTE The same samples can also be used for statistical process control (SPC) of the instrument. 3.5 recalibration samples very homogeneous samples at both low and high concentrations in the calibration ranges to be used for re-calibration of the spectrometer
5 NOTE 1 These samples are measured during the calibration procedure and the intensities obtained are stored in the computer as indicated in the manufacturer's instructions. NOTE 2 No chemical analyses are necessary, but the homogeneity of the samples should be carefully tested. 3.6 quality control sample sample with known composition which is analysed in the same way as the test sample to check the trueness of the analytical results 4 Principle Measurement of the intensity of the radiation, whose wavelength is characteristic of each element, generated by the spark resulting from the application of an electrical discharge between the sample, as one electrode, and an inert counter-electrode. The intensity measured is compared with the calibration of the element intensities and then converted to the element content. 5 Apparatus 5.1 Optical emission spectrometer Spectrometer with spark source capable of measuring the intensities of the optical radiation emitted at specific wavelengths by the elements present in the material. The wavelengths generally used are given in Annex A (informative). 5.2 Apparatus for sample surface preparation The most common surface preparation techniques for copper and copper alloys are turning, milling or grinding, the last only for copper alloys, provided that the composition of the surface shall not be influenced. The lathe, milling machine or any other machines used for surface preparation shall be able to produce a sur-face that conforms to the requirements of 7.1. WARNING — The appropriate safety recommendations for the use of mechanical apparatus must be observed. These operations shall be carried out only by properly trained personnel wearing appro-priate personal protective equipment. 6 Sampling Sampling shall be carried out in accordance with ISO 1811-1 or ISO 1811-2, as appropriate. The sample needs to be sufficiently homogeneous with regard to the spark impact. The analytical surface should be free of pores, cracks, sinkholes and slag inclusions.
7 The calibration is normally done when the apparatus is installed. The calibration shall be in accordance with the spectrometer manufacturer's instruction manual, using the appropriate certified reference materials, if available. If no certified reference materials are available, reference materials with an accurate analysis shall be used. The trueness of the analytical procedure is checked by measuring a set of certified reference materials or — if not available — a set of reference materials not used in the calibration. These reference materials shall cover at least the low, mid and high points of the calibration range for each element. 7.2.3 Recalibration Drifts of the spectrometer readings shall be corrected using a recalibration procedure as described in the manufacturer's instruction manual. Recalibrations can be done either for all analytical channels (global
recalibration), or only for individual analytical channels (selective recalibration). Recalibration can either be done periodically or due to a deviation from statistical process control (SPC) limits (see 7.3.4). When a periodical recalibration procedure is used, the period depends on the stability of the spec-trometer and has to be established by a stability check of the spectrometer. The stability check shall be re-peated at appropriate intervals. NOTE The same set of check samples can be used both for drift control and for statistical process control of the spectrometer. After recalibration, a set of reference materials not used in the recalibration procedure, shall be measured. 7.2.4 Type recalibration Type recalibration offers a further possibility of correcting instrument drift and, in addition, for matrix influences. Here, one or two reference samples of the same material type and of comparable composition are analysed, together with the test sample. Subsequently, by means of linear correction, the contents of the test sample are related to the certified values of the referenc
